Airlines need to give it up, stop angering people, and just put in a row of fat seats in the back. This is stupid for business.
The airlines just need to increase the size of their seats to what they were in the old days. The average size of people has increased. That woman isn’t the norm. There are many jobs in which the people are larger. What if this had been a firefighter, longshoreman, police officer, construction worker, etc?
Also, people keep missing the point that the woman was flying “standby”. She did not have a seat on that flight.
